HRAP EX easy noob questions

Hi all thanks for at least reading this far. I’m going to keep this short and sweet but with enough info to hopefully get answers without having to answer additional questions which can be a pain. I’m new to the whole arcade stick thing for the consoles. I have a HRAP EX on order. Basically I have done my research and come to the conclusions that I’m going to replace the 8 bigger action buttons with sanwa buttons. and I guess the other two smaller buttons as well. My questions are what size are the 8 bigger buttons and the two smaller ones so I’ll know which sizes to order and should I buy a new stick? If so which kind. I prolly stick with the square gate unless octagonal is so much better. OH and will all ball tops fit on any stick? Thankyou again. Any input will be helpful.

P.S. Replying with "whatever works for you " doesn’t really help because I’m a NOOB. Nothing works so far. Thanks again. And yes I have read other threads.

Sanwa OBSF-30 for the big buttons, OBSF-24 for the little ones. Sanwa and Seimitsu balltops will both fit.

replace the stick with a JLF and send me the old one.

If you decide not to use Sanwa, then any 30mm buttons for the big ones, 24mm for start/select.

Edit: I don’t know what the inside of the HRAP EX looks like, you might have a little difficulty with screw-in types.

You’re awesome thanks so much.

I actually think the HRAP EX already comes with a JLF, so just stick with that.

it does??? OMG

JLF-TM-8T-SK-K the HRAP EX comes with.

…sarcasm didnt take 'eh.
