I would get the 36hp Vanguard. I have had the 32 and the 36hp now on an XP, and its a big difference. I know its a little more for the 36hp, Its $8399 on the Bad Boy XP or like $8799 with the grammer seat upgrade on the 61", but its worth it. I have a 36hp on my demo and everyone is blown away buy it. I sell way more 31hp kawasakis on that mower, but the briggs is good stuff! And for the xp being slower, we put 21cc pumps on an xp here (instead of the 12cc it comes with) charged customer $500, and its pretty dang fast! not quite as fast as the super z with hyper drives (its the fastest one Ive been on stock), but its fast!...
