this is a good deal, if i dont have my gloves i would get these.
i have the gp-plus and they're really nice, i think i got those for 150 too or a little cheaper.
frong u should go to the store and try the large and medium out. i have medium and the wrist part is pretty tight (dont stretch), and if u have big hands it wont fit.
btw: i installed my yoshi slip-on today and it sounds really nice, rumbles at idle, roars until like 8k and then goes into a high pitch scream.
