T1, T3, MG4 below left to right. T3 is pretty much same size as MG4, T1 is smallest.
I ended up doing T3 48 (bent to 49), 54, 58. In the gap it's a no brainer with 225/245s (I have 225). The 54/58 both the T1 and T3 are great, I don't notice any real difference other than a little more forgiving feel on T3. Find the grind that suits you and go
