Thank you for your inputs brian and SoSmellyAir. I think I'll pass on getting a Gabba. I did find a screaming deal on the Sportful Fiandre Pro short sleeve jacket. This one uses Polartec Neoshell rather than Gore Infinium that Castelli uses on the Gabba and Perfettos. Neoshell is supposed to be very stretchy and breathable, and I'll be own test dummy to see the reality of the claims. I plan on using this the No Rain arm warmers. While I have other Sportful No Rain clothing, I do understand it's limitations as a water repelling treatment of the fibers as opposed to a barrier/laminate of some sort. I mostly use it for thermal properties anyways. I also understand the given temperature ranges of such garments, and that's acceptable as I have to wear something course, in those temps ! I used to be much more adaptable to wind and cold wearing just various jerseys but of late not so much. I do like the premise of the Tutto Nano jersey as I always thought since the thermal/water repelling Nano warmers were so good why haven't they just made a jersey out of a similar fabric ? Well done !
I've ridden in the Sportful Fiandre No Rain Lite short sleeve jacket since I posted this and did find having a rear pocket stuffed with something helped to keep the back from rolling up. I really like it overall as I really see it as an extension of a wind vest, one with short sleeves, if you will. It will be very versatile and stuffable. The Lite version fabric is very stretchy and conforms to the body well. I've not ridden in the Fiandre Medium jacket with it's No Rain fleece back panel yet, but trying it on and riding it around my yard I found my initial reaction was a bit rash. Speaking with Sportful it is supposed to cling to your body and may feel awkward as first in the shoulders. After riding with it on, with a Craft Extreme long sleeve baselayer underneath, I think it will be alright. I'm used to having wearing loose fitting jackets that slide(and flop) against the skin, and this doesn't, by design. So it's a matter of throwing out past expectations.
Wearing form fitting jackets is all new to me, believe it or not, and I have to say I really like them.
