Im going to be demoing them in a few weeks after i see the review of the RDX 500 and just had a thought? If i do like the MP tour-1 90 and buy one im afraid that it will be discontinued in about a year and that it will be hard to find one in case the one i bought broke? Do you think that it will be more than 2 years before it is discontinued? If longer how long would you say? Also for Chris i asked in another thread but didn't get an answer(not to be rude) I asked how many grams of lead tape you put at 2 and 10 O'clock each and also if you counter balance it by putting lead tape under the grip and how many grams you put on it if you do? Sorry for all the questions but thanks for putting up with them.
