What is your recommendation for some pretty tough tent poles that could be applied for huge pyramid tents like the Hyperlite Mountain Gear (HMG) UltaMid 4 or Locus Gear Khafra Grande?

The UltaMid 4 requires a pole length of ~75 inches (190 cm).

The original HMG pole does only have a diameter of 19 mm, which appears a bit small considering that length. Even worse, they have a horrible adjuster locking mechanism where the full load is forced on a small metal pin that pushes against the thin carbon tube walls.

Ruta Locura has recently updated their adjuster locking mechanism of the 710, 820 and 950 series to a way better solution with a lever clamp. Therefore I would prefer Ruta Locura.

Since the Ruta Locura 710 series would only have 18 mm of diameter, they are recommended for 3 season usage only (when using lengths above 73 inches/185 cm).

If we step one level above and go to the 820 series (what Ruta Locura recommends for 4-season usage), they have 21 mm of diameter while only slightly increasing the weight.

Question 1: Does anybody here have experience with the 820 series? Are they stable enough?

Question 2: Would it be totally overkill to even go to the 950 series with 24 mm of diameter? I don't want to mess around with unnecessary lightened tent poles that may collapse. Therefore I am searching for something "solid".
