Hi there,
I am planning on getting a backplate cut based upon the Roger Lacasse design. I managed to find a CAD version of the design on the 'Net. I am now wondering why the topmost slots (for the shoulder straps) are horizontal?
Does this not result in the shoulder straps rubbing your neck? I did a small test run with 2" webbing and the angle that it has to turn through to make the 45 bend and then the final slot results in the straps actually converging towards one another.
For example, check this picture: http://dir-diver.com/pics/backplate/reach_backplate_large.jpg
The straps seem to be turned down into the diver's neck. The strap remains horizontal and does not seem to "give" much. Surely this is a pressure point?
Again, at the UKRS site, the straps seem to be parallel or converging:

It seems that, to alleviate this "issue"(?), some people cross the straps over:
http://www.ukrecscuba.org.uk/ukdiver/harness/aa_harness/dscf0006.jpg
Is this a non-issue? Should I rather have gotten more sleep last night? Should I do something now in the design stage to get rid of this peculiarity? Would it cause other problems to do so?
Thanks for the help.
Cheers,
Andrew
