I just bought my first fibreglass hull from Steve G and it arrived last week, it
all looks to be of excellent quality, I asked Steve himself about the CF options and his personal suggestion was to go with the regular hull and with CF reinforcement in key areas, with all fibreglass products you will have some surface prep work, filling pin holes and mold half blemishes, all typical stuff, as for fuel tank locations and stuff, I've never been a fan of plastic fuel tanks as they've given me too much grief over the years, ever since I started using Walt Barney metal tanks I haven't had a single issue, also what I like about them is when you doing your build and set up, depending where your CG is working out you can place your fuel tank where you like or need it, this does mean that you will need to cut into your hull where ever you decide to place it, with having Steve do it and using the plastic tanks it's clean and taken care of already, boils down to your choice and preference. As for handling and performance there is one one other guy in our club who has one of these hulls and it works really well and it's nice and light, as for performance in general and for every scale I have had its final performance is always found in its set up and balance, always tons of testing and tweaking has been required and to find the sweet spot, a poorly set up boat is a pain in the neck,
a well set up one will make you smile, best advice I could give is take your time, think and plan out every piece and to get it as close to right before you go out for its first test runs. Check in with and talk to all your local scale guys, they are a wealth of information and knowledge and love to talk about their babies.
