Thanks for the input guys. I guess I should have been more specific. Maybe included side button and bottom button types to each choice.
For me it's telescopic with buttom firing button, like the GMS mod. Love that thing.
Definitely bottom firing, but I think it comes down to the overall design of the mod in terms of multi-tube versus telescoping. I have a nemi (multi-tube) and I love it's sleekness. I also have an astro and the telescoping look just suits it (with a steamboy as a topper it's my Jules Verne setup).
