Joysticks advice (newbie)

[Blueic5]

Hi

I've been building my cab for a couple of years now,  anyway I thought I'd start on the Control panel.   I've built the panel based on lusid design and 3/4 "mdf.   So joysticks I'd rather mount from underneath to save routing as I just for now plan to paint and seal the top. Games I like are sf2, final fight etc but want play other games too.   So initially was thinking a sanwa jlf but sounds a faff changing between 4/8 way and I'd need to route the top.   Came across the ultimarc u360's ball tops and they appear to be bottom mountable.   I see they do a top restrictor too which maybe useful and give it a nice feel.   Is this my best bet will the throw be to long?   Do I need to change the spring?   Suggestions please   oh and these would save me buying an ipac for now.

U360. Octagonal restrictor. Stiff spring. Lube the pivot with plumber's silicone grease. You're welcome.

Thanks,  would I need the longer shaft?   I take it you would go with this over the front mounted restrictor kit?
