B44.1 is a much easier car to drive...the 410 is an aggression monster!!! IMO
The engineering on the 410 is def very pretty looking, I've always lusted after them on that front, but the design of the 44.1 is so easy to work on, setup and build, and a few run them at the club so a bit of advice and support to be had.
There is normally a 4wd heat, but normally only 1 heat. The 2wd drive class has 2 or 3 heats so there is a better ability spread, and the heats are better grouped ability wise...the 4wd heat has the fastest and slowest guys all in at once...which is interesting at times lol.
Either way, be great to see another regular, def get yourself along before you spend any cash and come have a chat, and see how things run!
