Porl, Those I mentioned have more beef in the blades. I am not much of a Dovo fan. I prefer a Wedge style (3/4 hollow) to the thinner hollow ground razors.
I think a 6/8 or wider is more suited for me.

You have a great razor in the TI. They are not entry level razors. Just no frills. If you closed your eyes you could not tell the difference in a $1000 TI and a $100 one (except they don't make a $100 one).
