Worst case all you need to do is put them on a truer. If not then you'll save a few pennies because they're slightly less than the Jaco branded ones.
Xceed foams are not made by Jaco and never have been. Xceed make 8th tyres, and their compounds are based on that. They aren't badly out from the box, but a true on the truer is needed to make sure that you have the same diameter side to side, and true tyres.
They're good tyres. They don't chunk and split as easily as Jaco, and they give excellent grip. However, they are probably 0.1/0.2s per lap slower than Jaco, but much easier to drive. I find I get a better time over eight minutes from Xceed than Jaco because I am not always on the edge of my talent! I am a C/D finalist at UK Nationals, and have been making some progress up the lists using Xceed because they are more consistent to drive. HTH

what is best, a high rev or high torque motor for 10.5 blinky
lap times in the second half of run were 0.4sec slower than at the start, is that due to addative, batteries or the motor getting hot (60deg)

What is best is the motor with the most power. Power is torque x revs, so a motor with revs can produce the same power as a motor with torque. It doesn't matter which one you have, as the speed you get depends totally on gearing for the track layout. I find GM motors very tolerant of high heat so you can gear them up a bit and find a bot more top speed for an open track. However, for a tighter track, you have to gear them down, but then they will accept more timing. HTH
