I certainly wouldn't buy another bag just for the few months of summer, just unzip it and use like a quilt if it's a bit warm.

beat me to it Sean.

Don't worry, they confuse everybody. Everyone is different. When i'm buying a new sleeping bag, i tend to look at down weight and loft and compare that to what i have been happy with in the past. Compare the Skyehigh 600 with what you have used before.  If you're not sure of how warm you sleep, then it's a bit of trial and error till you find what works for you. A Rab Quantum 250 with a temp rating of 0C does me spring to autumn and i wear more clothes on colder nights.

Wat till you get the 'weight-loss' bug, then you'll have a set-up for every temp.

PKeith - do you own this bag already?

I use it for winter camping - abeit with other gear. I can sleep in my clothes in summer with just a bivvy bag for insulation at night. But everyone is different.

The best bet is to sleep out a few times work out what comfortable and add a few layers per 1000m ascended. 

I always add clothing layers. They are more useful than sleeping layers. 

It also depends on the weather... Was on Arran 3 weekends ago and their was ice forming on the tents in the wee small hours, so we were actually quite glad we'd been wimps and put our thicker bags in, even if we didn't do the zips up (those are bags rated to -12 or so, and obviously weren't "too hot").

I didn't see much point in a separate summer bag until I saw a Bargain.  Cotswold had Dewlines for £100, and since I am a sad gear junkie it seemed rude not to...  My usual Lightline isn't exactly huge and weighty, but the Dewline goes substantially smaller and lighter, and that means a smaller, more comfortable rucksack and/or more packing space for other comfort-makers (e.g., beer!).

Pete. 

If you were happy with the ME skywalker, measure the loft on it, and get a new, lighter, less pack volume bag with similar loft.

Not for the first time on this forum, I'm glad I'm not the only one. I too have an ME skywalker II, which was amazing when I first got it but now I'm considering non-car camping... well the pack size is impressive, isn't it?

I was idly considering a pipedream 600 so as to cover all my bases - UK Winter and Summer use: I would like to avoid more than one sleeping bag purchase if I can, the pack size matters, the weight (right now) isn't the major priority right now.

So no, I don't think you're indecisive. Oh hang on....

Sorry to throw another idea in the pot PK, but can you wait until Autumn till you get your bag?

Alpkit are bringing out a Pipedream 200 pied d'elefant style bag for £60ish that weighs 460 grams with a -3 comfort rating. You have to use it with an insulated top, like a down jacket or similar, but most people carry this with them anyway and take it off to go to bed. Alpkits own jackets are £50 now I think... if they have any left.

I was lucky enough to get the PD200 in their CoLab Development thing they do. I can get the bag, down jacket and bivvy bag into a compression sack that cinches down to less than the SH600 sack. The whole thing plus a 2L Platty only took up just over half my 25L running pack!!  

The downside is that you might get some jealous looks from folk sweating it out with those oversized 35L packs though!!!!

Rocky your pack for the Skye wildcamp was very impressive mate wish i could get my rucksack down to that size.

..

Ha ha, to be honest mate, I'd never done that setup before. I couldn't believe it when it all went down that small, I nearly shagged my pack with pleasure!!!
