Back to the interesting question: Do the Trip have more power/grunt than the Bandit, both in 10 m2?
As said, you will get a lighter kite that can hang easier when sub 10 knots, but you might not get a kite where you can ride in less wind than your bandit - maybe just the opposite
Noone has answered that question yet...
But the Trip will be much better to handle in wind just under 10 knots, doesnt drop as easy and will feel "light"
Personally I must say, 9-10 m2 kites most often works well with our "normal" kites for hydrofoiling, as used from 9 knots and up where they work just fine, unless it is a really heavy freestyle kite of course
But in sizes 11 to 13 m2 our "normal" kites are useless for foiling with typical wings, so go strutless or 1 strut or superlight in these, which are the sizes used by most riders when just under 10 knots.
--------------------------
Oh - I just saw now, the Space Skate H4 is whopping 1500 cm2 - then I take all I said above back, and think you should go with the 10 m2 Naish Trip, should be no problem at all in 8 knots, IF you can waterstart that is, can be the tricky hurdle left in low summerwinds, but once up it should work perfect with that size wing and you need a lighter kite than the Bandit now
