FYI -To clear things up, Anderson made 4 different Nanoteks:
SP (11026) - one piece singlewall, not ASA approved, slight end-load
SPA (11027) - one piece singlewall, ASA approved, very balanced
SP Alpha (11030) - 2-piece singlewall, ASA approved, composite handle, singlewall balanced barrel
SP Omega (11031) - 2-piece singlewall, ASA approved, composite handle, singlewall endloaded barrel
All of these bats are extremely hard to find.
*Demarini Steels are all 2-piece bats including the new Steel (steel handle), older Raw Steel (steel handle), & White Steel (composite handle)
*The Corndog, technically speaking, would not be allowed since it is a 2-piece bat (composite handle, wood barrel)
*The Evil Protoype singlewall was kick-ass. Felt like a very endloaded Ultimate Weapon with smaller Anderson type knob. Too bad these never went into production
* Be careful when buying an Easton Salvo Scandium or Ronin as Easton does a terrible job of distinguishing bat characteristics within their line-up (I.E. the "Ronin" name includes the Ronin flex which is a composite bat and a Ronin ATAC Allloy which is the singlewall)
**Those 44/375 softballs will basically eat up any singlewall bat. If you are a heavy swinger be prepared to go thru them fairly quickly, especially the Ultimate Weapons, & Eastons. The Andersons will give you the best durability.
I would rate one-piece singlewall ASA approved bats as follows (just my two-cents):
#1 - Anderson Nanotek SPA (good durability, small sweet spot but when find it the ball goes far, balanced) - hard to find
#2 - Rip It REAP5 (best durability of all 1-piece singlewalls, good pop but not a lotta feedback, endloaded) - hard to find
#3 - Easton Salvo Scandium/L9 (average durability, good pop, very endloaded) - not produced anymore but can be found
#4 - Demarini Ultimate Weapon (poor durability, good pop, cheap, balanced ) - easy to find (new ones go for about $140, older ones <$100)
#5 - Anderson Flex 2018+ (do not buy any pre-2018 models, very durable, ok pop, balanced) - easy to find, still produced
#6 - Old school metal such as Ritch's Superior, TPS Powerdomes, Anderson Flextech/Pyrotech/KSP -harder to find
#7 - Easton Ronin ATAC Alloy (average durability, ok sweet spot, balanced) - easy to find (this bat just did not work for my swing)
Hope this helps
