I would stay away from the TH 46, it is a crapshoot with the engine. Also, for a newbie, the engine break in procedure is pretty complex. I had one it never worked right, tower sent me a replacement and it never worked right either. Since then I have had 2 TT pro 46. Super easy break in right out of the box its a super engine, never one deadstick in about 5 gallons of fuel between the two.
