That's probably a bowline ("bolun"). It's used extensively in sailing because of its strength and ease of untying, however all knots will reduce the strength of the line significantly. A splice however, can retain up to 80%-90% of the line strength. Given the strength of dyneema though, you could probably still have a good safety margin for an elevator even with 30% of the breaking strength, due to knots.

Dyneema is great stuff, highly recommended.
