International V 50VSW or 50 VISW?

[rebait1]

I'm trying to figure out which to sell which to keep.

These are for trolling NJ. So YFT, BigEye, and of course BFT.
The weight diff is 75 ounces vs 67. I'm leaning towards keeping the lighter reel(s),

Is there much/any difference? I've heard that build quality is declining.

Here are a few specifications comparing the 50VSX and the 50VISX. I don't have any empty reels for the wide versions.  There are a few obvious cosmetic changes.  Here's the biggest change and it isn't cosmetic.

Gold 50 VISX Frame width at the spool: 62.2mm.  Spool width at the rim: 58.7mm

Silver 50 VSX  Frame width at the spool: 53.1mm.  Spool width at the rim: 50.6mm

The shape of the spool at the bottom is different, a little more "V" on the VSX and a little more wide "U" on the VISX.  There is also a textured knurled strip to grip line on the VISX.
