point to note on that front, there's rose joints and there's rose joints..
I've got them on my clodbuster and trust me if you cheap out they jam up quick and easy.. they even feel cheap and sh1t when you twiddle them in your hand. a lot of 'upgrade' RC parts are very cheap.. to be fair they're not under a lot of strain, and you only use them once in a while not a hundred times every day
personally I'd spend a few quid on decent rose joints. then you just need a bit of stud and if you wanna go really posh get some tubing to go over the stud and make it look nice
for example
2 x
rose joints
1 x
m3 stud
1 x
outer tubing 4 or 5mm OD ?
