Just like the title says I have a sanwa mt44 right now thinking about getting a m12rs. What are your opinions? What difference will I notice. Thanks

M12 is big and heavy personally I prefer mt 44.

They are the same speed wise. Some additional ergo options with it though. (BTW, the RS doesn't come with all the ergo parts in the box. The S does)

Ha Ha. I just shelved my new M12s-rs for an MT44. Used it once. Might be going up for sale.

The M12s is faster response than the MT44,the RS comes with the most widely used options of the M12s and is the same response. If you want the best then the M17 on SXR mode is the absolute fastest response and connectivity

The MT44 is a light weigh fr sure. I run a M12S and really don't notice the weight. I am left handed, so my options are limited. The M12S is very fast, you can really feel the connection with the car, just an unreal feeling, love it.
