I'm really happy with my Fischer boots, I've still got the old 9000 ti race, which was sold as consumer boot but in fact more of a plug than most semi-plugs out there. It's built like a tank so I think it will last plenty long (maybe as long as my Raichle Snowboard hardboots which after 300+ days still do well, though needed many parts replaced).
If your an overpronator, Fischer boots provide an answer. They were designed mostly by Herbert Auer, and Christhoph Leitner who are probabely the most prominent bootfitters for worldcup skiers and snowboarders (esp. Leitner). So the V was not invented for marketing but their opinion on how boots should look like (it was first sold under the Rexxon brand before they moved to Fischer - production is at Garmont). Besides the V Fischer boots flex in a slightly different direction than other boots, which makes a difference too.
The newer boots are way softer than the old 9000 liner, but the Worldcup Pro is still plenty soft. In Austria loads of unsponsored racers switched over to Fischer boots, and they replaced Atomic as being the most popular boot for amateur racers it seems to me. The good thing is that the Heat and RC4 line is one of the very few boot lines for narrow feet which is not stiff like semi-plugs or plugs.
Taking into account that Fischer doesn't require its racers to use the boots, most of them moved to them by now and that didn't seem to hinder their performance. Niki Hosp who won the worldcup last year has been in Somatec boots custom made by Leitner since her youth (first Custom cutten, then Rexxon now Fischer) and she's not sponsored by Fischer. What I heard is that Fischer doesn't make that much money on the boots (compared to skis) as they are OEM from Garmont, therefore they supposedly don't pay any racer to use them unless they ski on Fischer skis too.
Try any of the Heatfire or RC4 models. They are indifferent except for the color options. The liners are pretty much the same throughout the whole range too, only the flex numbers make the difference.
There are 4 different shells by Fischer in total. 1. the Worldcup Pro. 2. RC4/Heat, 3. The Soma MX-Pro and MX boot got a different shell, and 4. the lowlevel MX 5/7 again got a different even wider shell.
1. and 2. are pretty new, while 3. and 4. are still the same from the beginning.
