so if i go for the 15/43 option will the bike give me more top speed because it can pull back up into the power /torque range in top gear?

It depends on a number of factors, but essentially you've got the right idea. To reach the highest to speed you need to keep lowering the gear ratio until you max your terminal velocity concurrent with your red line. Trial and error will give you the answer. The biggest factor is air drag which quadruples when you double speed. 15/43 is a nice all-round ratio, but probably isn't the best top speed ratio.
