The "load block assembly" is defined in rule 4b as load block, and eyebolt, and wingnut, and S-hook, and chain, and 5 gal bucket. Any tower that can't carry 'the assembly' is to be classified as Tier 4.
A carbon fiber arrow shaft is going to be....way lighter than eyebolt, wingnut, S-hook, chain, and bucket, so if a tower can't support it, its a Tier 4 tower. Yes, if using this tool to check height, students should place it on the tower.
I've been instructed that "eyehook" is actually 2 words... "Eye & hook" I assume that eyebolt and wingnut probably are too... I think you are OK with hyphenating the S-hook though... LOLOLOLOL
