[Closed] BB advice needed - hoping to buy once despite upgrades.

Hi, my bottom bracket sounds like it has broken into bits, if it does need replacing I would like the new one to work with my current and planned upgrade chainset.

Frame = Pipedream Sirius (73 mm bottom bracket shell)
Current Chainset = Truvativ Blaze 2x9 Chain Set With Truvativ Powerspline BB
Possible Upgrade Chainset = Shimano XT 2x10
Intended BB = Hope Bottom Bracket MTB 73mm

I'm aware of the existence of a Hope Bottom Bracket Truvativ GXP Converter but don't know if this applies to mine. Is the 'powerspline' bit a problem?

I'm basically asking if I can use the Hope BB (with or without the converters) now and use the same BB with the XT chinset?

Thanks in advance.
