Which flame arrestor? Riva vs K&N

[PitStop504]

I just picked up a 95 SuperJet to replace my trusty Kawasaki 550. Both skis have BN44s. The SJ came with a Riva flame arrestor with a wire mesh/cotton guaze construction. Its a little dirty and ratty looking but no holes in the filter.
The 550 has a K&N oval flame arrestor with a water-resistant cover. Which would you guys run?

Scrap both of those. Stock at any cost.

a particulate filter in a ski is the worst thing you can do,the carbs reverb out oil and gas,clog the filter,get even worse when wet, a wire mesh prox or stocker is the only way to go,those outer wears are just as bad,and totally useless

Garbage old school crap. Use a stock 61X air box, use only 1 screen instead of the 3 that come in it.

Thanks for the advice, guys! I'll be putting a stock one on ASAP

I wouldnt have guesses the stocker screens would impede flow,they seem so large.one screen enough to stop the flame on a backfire?
