Aaron, you already have a really well-recognized SL brand going (well, as well-recognized as a niche within a niche can be), so I would like to see you leverage your position in the market and develop it even further. You say that Pinhawk isn't just a SL brand, but maybe it should be. If you made it so, it wouldn't stop you from developing other lines.
I would love to see a company specialize in SL irons, offering different designs, specs, and mix and match options (e.g., CB/MB mixing). 1IronGolf has moved a bit in this direction, but I have a few different problems with their approach (even though I think they do other things really well). Just because I want to play SL doesn't mean I want to play shovels or thick topline irons. I'd like options.
But, then, I'm just one guy, and I don't even spend much money on clubs, so I may not be the best gauge.
