Hey guys, Currently have a canon 450D in ikelite housing and use Tokina 10-10mm fish eye for wide angle and canon 60mm for macro and I have a Ikelite DS 51 Substrobe. Obiously I have read that the DS160 is more powerful but I was wondering 'how' is is better? What improvments would I expect to see with lighting? If I was to get the 160, could I use the DS51 also? Are 2 strobes better then 1 ? Look forwards to hearing any suggestions

???
