Ok, that is easier info to work with - so if Gliding is #1 - then the Glide 1085, which will feel considerably smaller than your 1305, but not a massive gap to the 905 in terms of speed - but will add a nice amount of glide and for sure turns far better than the 1305. When I use the Glides occasionally or during testing other foils, I like the 905/1085 the most and there is definitely enough of a gap between the 2.
Carve 2.0 1100, not as good in Glide as the 1085 Glide, but faster and will turn tighter. Gets up and goes earlier than your 905 Glide for sure. Similar get up and go to the Glide 1085.
Whizz we have 1000 or 1200. 1000 will not get up much earlier than your 905 and will be slower, but turn tighter. 1200 will get up later than your 1305, but earlier than the 905. Compared to the 1085, similar get up and go, but slower, turns tighter. 1000 Whizz too close to your Glide 905.
Finally, replacing your Glide 1305 with the Carve 1430 - yes higher speed for the Carve, get up and go probably same/maybe slightly better for the Carve actually. Glide 1305 better in gliding/pumping, turning on the 1430 far better than 1305 due to the lower aspect. So maybe an option to switch to Carve range in 1100/1430.
I personally ride 650/850/1100/1430 Carves, most of the time I end up using just the 850/1100 like this past weekend at Garda. But in strong winds recently on Maui/Cape Town, the 650 is a nice backup for 3.5/3.0 weather or powered 4.5 etc.
But I am quite a bit lighter at 75kg, my priority is speed/jumping/turning. Glide not so important for me, as I can pump fairly well if the wind drops/to get up and go.
