I'd be looking to use this with my Southpaw 65 (65%, with a numpad on the left side) when it gets here. It looks like I'd need base, nav, ortholinear (for the 1U R4 ctrl and alt), and arrows. I'd still be missing the R3 PgUp, R4 PgDn for the 65% portion, and I'd have nothing at all for the numpad. I'd be interested in seeing the R3 PgUp and R4 PgDn added to the Nav/65 kit. If I have to buy the ortholinear kit for the ctrl and alt kit, so be it, but those would probably be good additions to a 65% kit. However, it's the absence of a numpad kit that kills this for me. Admittedly, that's an oddball keyboard I'm looking to cover, and I'm probably better off hoping SP restocks Alps Granite.
