The only thing that will suffer because of hollow grind is chopping. Edge will probably be thinner so might be a bit more prone to chips or rolls, but also will be easier to sharpen. Tensile strength will be very comparable to convex as both grinds aren't flat. Balance might be a bit more forward with the I-beamed handle. All in all, will be almost the same as original TG.
And I'm sure that Jerry would not put in production a knife that would be inferior!
