You should be OK with a 1.5 - I don't know the exact shot count, but that's the bottle size Smart Parts market themselves for use with Shockers & I'd guess they'd know!
As far as the low pressure mod to the AIR, it's a 1 minute job & isn't difficult at all. There's no parts to swap/add, it's simply a matter of removing a couple of the spring pack discs.
The mod apparently works best on the newer style AIRs - the ones with the raised dome on the front face of the reg - but can still be done on the older models.
If you need any more help then let me know.
