Spellstrike only works with touch-range spells - you are correct.
I've never seen anyone try to use those spells with spellstrike - spell combat is a different story, of course.
AHHH ok. Thats what i was missing.
So someone could use spell combat to THWACK and bladded dash or bladed dash then thwack ? (but NOT bladed dash thwack thwack) ?
Since spell combat allows a full attack before or after the spell being cast, and since Bladed Dash allows an attack as part of the spell effect, then yes, you could at 4th level when they get the spell do Bladed Dash thwack thwack.
