WHS^^^
Dont bother Bert, the weight differance aint worth it
You could save more weight changing to lightweight tyres, rotating mass and all that, you'd feel the differance, ti axle in yer cranks would save a few ounces but doubt you'd be able to notice it when riding
That my 2 bobs worth... :daumenhoch:

If I use the shortest Ti Spindle, Ti Flush Crank bolts and Ti Chainwheel Bolts, Flush kit, Hop Up kit and 180mm Arms it weighs 997g
If I use the Normal Spindle, Flush Crank bolts and Chainwheel Bolts, Flush kit, Hop Up kit and 180mm Arms it weighs 1175g
Ti versus Cro-Moly saves nearly 180g for this Crank Set (excludes Chainwheel and additional Aluminium washers and pedals)
This Ti Setup is 15.2% lighter!!
