Nils,
I'm still re-booting the cerebellum, it's quite a bit different than GS#1 with the 225X PM. Much more responsive, trim seems a lot quicker, and the 15" mid has lowered the CG. The weather is not cooperating much though, which is making seat time harder. Only three times out since launching in May. Temp wise it's been fine, but a lot of rain & wind.
BUT.... mid-range with the 26p Q4 OT is amazing I've seen 7-8mpg on the monitor at cruise, (2800-3000 rpm @ 30-38mph).
Haven't had the 28p Q4 on yet, but really, top-end isn't a priority for us, (the on-board trip computer sitting next to me see's too that),
The new 25p Q4 Round Ear hasn't even been wet yet, can't wait to see what the hole shot is like.
I'd rather be quick than fast......
FWIW.....Glenn saw 88.7 with a 'worked 28 Thophy+' when he water tested after rigging.
