I have a stunt Sentinel LE v4 in SY with windows and I love it!
The yellow blades is sweet and it looks great with the gold on the hilt.
I like the look of the yellow color much better in the standard (silver) mid-grade blades. Because the ultra-edge blades make it look washed out and give it a cream sickle look that I do not care for.
This goes for all the warm colors red, yellow, orange etc. This is just my opinion, others may say different.
I also got the lithium-ion batteries so the blade does not change colors as the batteries die out.
So that being said you will have to get premium sound to get the lithium batteries, which is worth it IMO. If you get the lite sound the saber will change colors as the batteries die out. This is with all mixed colors AB, SY, VA, and so on.
I also have a stunt Dark Apprentice AB with windows and the AAA batteries. I like this saber very much also.
It looks good in both standard and ultra-edge blades.
I won this saber so I did not pick the setup, as I don't care for all black sabers with Jedi colored blades, blue and green, but that's just me. The blade changes from AB to green as the batteries die out because of the AAA batteries. But I am not complaining because this was a free saber as I said .
Thanks you to Ultra Sabers for the free saber.
Both sabers are very bright and both look great IMO. Both handle very well. So it really come down to what you want .
Hope this helps and MTFBWY!
