The ability to side hop fairly high doesnt really make a great deal of difference at a comp.
Having seen riders of a very high street (tgs) ability completely fall apart in comps and struggle on anything slightly off camber shows its about all round skill, ability to see lines on rough terrain and postion the bike well on awkward objects. Im by no means suggesting you'll be like that btw! Maybe try an intermediate level. You may breeze through and be able to take on red route, but you'll get a confidence boost from being able to step up, rather than feeling deflated and dropping down a diificulty level.
Also think about, can you rush your riding? Sections will be held to a time limit, you'll be tired from possible long sections, arm pump may be a factor? Whats your fitness level like? Lots of things to consider.
Whack up a vid dude?
