Or the td06h has a much bigger turbine wheel I don't know y everyone loves the l2 my baby 20 spooled it 18 pound at 4200 on a 25 would be heaps better. Plus if you don't like the 20g power you can put the 25g wheel on and it's then classed bigger then the t67. Looking at the flow charts it's over 400kw classed. If you put the 25g wheel on yours it will then be the same spec as a t67 dori
