good choice. I am play a mrx5 too. hehe. For tires they are not too bad. GRP around 400-500hkd per pair including shipping. And they least very long time. Over 1 month while playing 2-3 times per week. BTW: If anyone wants to start play 1/5 and wants to buy tires. DONOT order the FG factory tires as they sucks. I tried GRP and they are very good. PMT as the have few different models, I only tried older model and it is not very good..... but from forum they said the new "superem" (sorry can't remember the exact name..) is ok.
