I’ll be honest right out of the gate in saying that I don’t have any experience with Senda.  But after looking at this ball, I will have to try one out soon!  Senda brings a very classic look to its ball, giving you a throwback to days gone by.  It has 32 panels and claims that it can be used outdoors, indoors, and on turf.  It is hand stitched with premium leather and has four layers of hybrid polyester and cotton linings between the cover and the bladder to help it last longer.  It is NHFS approved with its latex bladder, so it would be great for use in high school matches.  And especially considering it’s low cost.
The most modern feature is an embedded NFC chip, which is found on the top of the ball. If you download a free app on iOS or Android, you can personally interact with the ball's exclusive content and location-specific challenges. You'll also be able to participate and enter competitions and World Cup-related challenges. Of course, you can record and upload your experiences for social media posterity.
Latex bladders are one of the best materials when it comes to ball construction. However, with latex bladders, air won’t last as long as butyl bladders and will need more attention for proper inflation. Butyl-blend bladders hold in the air much better, but they are harder and less receptive in play. Mid-priced balls will usually have a mix of butyl and rubber. https://www.youtube.com/watch?v=c1SVcjYY6TE
